1. What is the principle of lifting clothes drying rack?
It is understood that lifting clothes drying racks are also called automatic clothes drying racks. They are divided into two categories: hand-cranked and electric. They are generally installed on the balcony and the drying pole is hung with a wire rope. When drying clothes, lower the drying pole by hand or electric method, and then raise the drying pole after drying the clothes, which is very convenient.
According to Residential Online, the lifting clothes drying rack is operated by a hand crank to pull the steel wire through the corner device and the top base to drive the drying rod, so that it can be raised and lowered. The hand crank has a self-locking function, mainly through The built-in spring tightens or contracts to generate friction, allowing the drying pole to automatically lock at any height.
2. What are the tips for choosing a lifting clothes drying rack?
In modern living, most families will buy lifting clothes drying racks for convenience. The function of the lifting clothes drying rack itself is very powerful. When drying clothes, the height of the lifting clothes drying rack can be adjusted according to our height. According to Residential Online, the tips for purchasing a lifting clothes drying rack are as follows:
1. Look at the pole: When purchasing, look at the pole of the lifting clothes drying rack. The thicker the pole, the better, but the moderate one. If it is too thick, it will be heavy to use and is not suitable for use as a lifting clothes drying rack.
2. Look at the material: There are many materials for drying poles, including stainless steel, aluminum alloy, silicon magnesium titanium aluminum alloy, etc. When we choose, we must look at more reputable merchants and remember to identify them carefully. Material.
3. Look at the craftsmanship: Surface treatments for drying include polishing, plastic spraying, electroplating, etc. Different processing techniques will also affect the grade and quality of the clothes drying rack.
4. Look at the pulleys: Look at the pulleys of the lifting clothes drying rack. The pulleys are made of ordinary metal, iron and copper, but the quality of pure copper composite pulleys is better.
5. Look at the hand crank: The hand crank of the clothes drying rack is the core component of our clothes drying rack, so when we buy it, we must check whether the hand crank is smooth to use and whether it makes a lot of noise. Illustration of the principle of lifting clothes drying rack 2
1. The working principle of lifting clothes drying rack
During the use of lifting clothes drying rack, the drying rod is moved by hand or electric method. Lift.
The principle used to lift the clothes drying rack is very similar to the working principle of the crane. It mainly uses wires to pull the gears and pulleys, and then controls the clothes drying rack to rise or fall.
The working principle of the automatic lifting clothes drying rack is based on the principle of manual lifting and lowering of the clothes drying rack, adding a motor, and using the motor as power to work, thereby freeing both hands and achieving the automatic lifting function.
2. What is the load-bearing capacity of lifting clothes drying racks?
Lifting clothes drying racks usually bear a load of about 35 kilograms, and some brands of lifting clothes drying racks can bear a load of up to 50 kilograms.
The main working principle of the lifting clothes hanger is to use the hand crank to run the traction steel wire through the corner device and the top base to drive the drying rod to lift. In addition, the hand crank has a self-locking function, and the hand crank can be controlled to allow the clothes hanger to be lifted and lowered. The pole automatically locks at any height.
Whether the lift hanger is safe and durable depends on the quality of the lift hanger. The quality of the lift hanger can be judged through the following points:
Look at the parts processing , high-quality lifting clothes hangers are extremely fine in detail processing, and the surface treatment of the drying rod is smooth and delicate, which will not damage the clothes and is not easy to oxidize and turn black.
Look at the lifting rope. The steel wire lifting rope for lifting and lowering the clothes hanger is generally thicker and has good flexibility. After being folded in half, it can be quickly opened and restored, and it is durable.
Look at the roller skates of the lifting clothes hanger. The pulleys move smoothly, smoothly and silently. Illustration of the principle of lifting clothes drying rack 3
1. Principle of automatic lifting clothes drying rack:
1. Clothes drying rack structure
The automatic intelligent elastic clothes drying rack is installed in the window The awning with the lower edge matching the clothes drying rack is installed on the upper edge of the window.
A steel wire rope is used to connect to the outermost clothes drying rod of the intelligent elastic clothes drying rack through the far end pulley.
The motor works in different directions, forward and reverse, to control the retraction and expansion of the hanger. The two ends of the three clothes-drying poles are connected by linking ropes to realize the linkage function when the clothes-drying pole is expanded. The front and rear ends of the left support rod are respectively equipped with sensor 1 and an azimuth sensor. The azimuth sensor is a Hall sensor.
2. Control circuit design
Because the automatic lifting clothes drying rack is installed outdoors, in order to complete the anti-exposure function of the clothes drying rack, it can detect the ambient temperature in real time and expand the temperature detection circuit. The high-performance temperature sensor DS18B20 is selected in the design. This sensor has a wide test temperature range and high resolution (the highest resolution can reach 100%). By connecting DS1820 with a single-chip microcomputer, the temperature can be detected to achieve the purpose of preventing exposure.
3. Key Technology
The automatic intelligent elastic clothes drying rack uses transformer rectification technology to convert 220V AC power into a DC power supply that can be used by the controller.
p>Use the microcontroller as the central processor to reliably control the forward rotation of the motor, that is, the retraction and extension of the clothes hanger. The type of microcontroller is 89C2051. The flexible clothes drying rack and plastic awning can be controlled through the designed control mechanism. The clothes drying rack achieves the purpose of automatically expanding and contracting as the environment changes.
2. The principle of the hand crank for lifting the clothes drying rack:
The hand crank operates to pull the steel wire. The corner device and the top base drive the drying pole so that it can be raised and lowered. The hand crank has a self-locking function (mainly through the tightening or expansion of the built-in spring to generate friction), which can automatically lock the drying pole at any height. Machine: This is the core component and power source of the clothes drying rack. Shaking the hand crank can drive the lifting and lowering of the clothes drying rack.
The self-locking principle of the hand crank: when it stops, it relies on the tension of the spring. The huge frictional resistance generated causes "self-locking". When it rises or falls, the spring tightens and reduces friction with the spring cup, so it can rise and fall smoothly.
3. Principle of ultraviolet light disinfection clothes drying rack: < /p>
The electric clothes dryer uses a low-pressure mercury vapor UV lamp to kill germs through ultraviolet irradiation and ozone purification. The low-pressure mercury vapor lamp mainly produces 254nm and 185nm ultraviolet rays for sterilization. : Ultraviolet rays with a wavelength of 254nm are easily absorbed by organisms and act on the genetic material DNA of organisms, causing DNA damage and causing bacterial death; Ozone sterilization:
Mercury vapor will produce ultraviolet rays with a wavelength of 185nm. Ultraviolet rays of this wavelength can turn O2 in the outside air into O3 (ozone). Ozone is a very active molecule that can easily undergo chemical changes with other molecules, causing re-decomposition and conversion into oxygen to renew the air, deodorize and sterilize the air. Purpose.
Scientific experiments have proven that the Orland electric clothes dryer can quickly and effectively kill 18 types of harmful bacteria such as typhoid bacteria, dysentery bacteria, coliform bacteria, staphylococcus bacteria, tuberculosis bacteria, and subtilis bacteria.
The electric clothes dryer can be intelligently controlled based on the amount of laundry, and will automatically stop when the ideal sterilization effect is achieved (usually it takes about 30 minutes for a family of three).
